A little at a time...... Make as good a B&W pic as you can. Forget
the color for now.
Be sure the cap on source #7 ( 4.7mfd ?) has been changed.
Put real content NOT a generator on it.
Turn off all auto color controls & color control all the way down.
Contrast & bright about 3/4 up.
Be sure you can turn the brite down all the way down to no pix or
very dim pix. If not turn down G-2 a little.
If it looks like it has bad convergence adj the H-STAT control.
Now go to manual & put R-B-G controls at the start point, Make the
pix as B&W as you can. Then we can take it from there.
BTW the lines you see are the phosphor stripes.
The CRT is a low focus type & moving the jumper seldom makes a difference.
You could use a pot but use a 1 watt & be sure it runs cool !
